Hi Marcelo,
During 'make dep', make spends most of its time (sometimes more than 75%) uselessly analysing .hdepend. Delaying its production makes 'make dep' much faster. The following patch also builds .depend last, in order to make the dependency information generation more resistant against ^C and other failures.
Regards,
-- Benoit
